VEHICLE-TIRE.

Specification of Letters Patent.

rovement in Velncle-Tires, of which the folowing is a specification.

This invention relates to vehicle tires, which are particularly-adaptedfor use on automobile-or bicycle wheels, but which may also be used onany kind of a vehicle wheel where considerable resilienc is desired,such as buggies, carriages, and t e like. I

The object of the invention is to rovide a tire which is adapted to besecure, to a vehicle wheeh Tll1S tire is provided with a plurality of:springs circumferentially arranged on the outer surface of the tire, andyieldably supporting a pluralit of shoes, all

lexible covering of rubber or other like material. This gives'a highdegree of-resilienc when the wheel is in motion and obviates thenecessity of using the expensive tires of pneumatic type in order toobtain the desired resiliency.

i ure 1 is a side elevation of my improved vehigle tire, partly insection; Fig. .2 is a top planin section; Fig. 3 is a cross section inelevation'taken on line m m of Fig. 1; and

Fig. 4 is a longitudinal section in elevation.

n the accompanying drawings the reference numeral 1 indicates thevehicle wheel to which is secured the tire 2. Walls 3 and 3" arecirculnferentially disposed on the outer surface of the tire 2 andformed integral therewith. Disposed at redetermined intervals on thesurface of t e tire 2, between the wallsSand 3- are the lugs 4 and 4%.The purpose of these lugs is to form a seatfor the reception of the srin which will be hereafter described. Slant ards 5 are also formedon'the outer surface of the tire'2, these standards are disposed.between the lugs 4 and 4*, andare provided withthe longitudinal slot 6.A s ring 7 is adapted to encircle standard 5 and rest in the seat formedbythe lugs 4 and 4.

The shoe 8 has formed on its under sur face, and intermediate the endsthereof the projections 9and 9", and on each end of said shoe are thedownwardly extending projections 10 and ll. The projections 9 and 9 forma seat which receives the upper end of spring 7 when the shoe 8. issecured in positlon thereupon. Intermediate of the seat formed by theprojections 9 and Q is secured a slotted extension 12, thelowerend ofthis extension is provided with opening 13. When the shoe 8 is placed inposition on the spring 7, the standard will pass into the slottedportion of extension 12, a bolt 14 is passed through openin 13, andthrough slot 6 into standard 5. When SI)1iI1'-7 is in position thestandard 5 and slotted extension 12 will be in their extended positionby reason of the ressure of said spring, which will readily yield whenpressure is exerted against the outer surface of the shoe 8.

As here shown, the center of shoe 8 rests directly over one end ofspring 7, and each end thereof rests upon one-half of the upper ltfl'surface of the springs 7 disposed on elt side of the spring locatedintermediate of the shoe 8.- When a plurality of shoes 8 are socured inposition as heretofore described,

the projections 10 and llon the ends of each shoe will form a seat forone of the springs? Ribs 15 and 15 are formed on the upper sur'- face ofshoe8. A rubber casing is adapted to inclose the walls 3 and 3 and theshoes 8, the inner surface of the casing 16 is provided with parallelgrooves 17 and 17 which re ceive the ribs 15 and 15. The tread of thecasing 16 is provided with nurls 18. The

ends of said casing 16 are provided with a.

plurality of openin s 19 throu h which extend the studs 20, iormed on te lower end of the walls 3 and-3, these ends are rovided with o enings21 which are provic ed with interna screw threads. A ring 22, providedwith the openings 23 isadapted to be secured to the studs 20 by means ofscrews 2 1, thus securely holding the casing 16 in position on the tire2.

It will be understood that ldo not wish to limit myself to the form ofsprings here shown, but that any form of a s ring may be used which willprovide the esired resiliency, hence I do notwish to be limited to theexact construction and arrangement of the springs as herein shown andescribed.

What I claim as new and desire to secure by Letters Patent, is-

1. In a deviceotthe class described the combination with a rim, of wallsintegral therewith extending vertically outwardly for a short distanceand then concaved to the outer extremities, lugs integral with-the rimforming recesses, springs, one seated at one end in each recess, shoesfitting between the outer ends of the concaved walls and conseatedtherein, s'hoes spaced a the walls,

forming t o=the curvature of the rim, inwardly directedjlugs integralwith the middle of the shoes form ng recesses, lugs, oneatfe'ach endof'eachishoeadapted together with "the end lugs of adjacent shoes toprovide recesses to; receive the outer ends of p part of the springstherein and. the outer ends of the remainder of'the's rings seated inthe middle recesses injthe sh and en aged around the c cal wal s of therim.

- .2 In a device of the class described the combination with a rimprovided with re cesses at-suit'able intervals a art, springs istancefrom the rim-{and conforming tothe curvature of the rim, Ieach shoeprovided with a central recess to receive the outer end of one of saidsprings therein, means at each end of each s oe coactingwith theadjacent shoes to engage one .of the aforesaid springstherein, a
